基于jeecgboot-vue3的Flowable流程-自定义业务表单处理（一）支持同一个业务多个关联流程的选择支持

因为这个项目license问题无法开源，更多技术支持与服务请加入我的知识星球。

这部分先讲讲支持自定义业务表单一个业务服务表单多个流程的支持处理

1、后端mapper部分

如下，修改selectSysCustomFormByServiceName为list对象，以便支持多个

"-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
"org.jeecg.modules.flowable.mapper.SysCustomFormMapper">
	"org.jeecg.modules.flowable.entity.SysCustomForm" id="sysCustomFormResult">
        "id" column="id"/>
        "businessName" column="business_name"/>
        "businessService" column="business_service"/>
        "flowName" column="flow_name"/>
        "deployId" column="deploy_id"/>
        "routeName" column="route_name"/>
        "component" column="component"/>
        "createBy" column="create_by"/>
        "createTime" column="create_time"/>
        "updateBy" column="update_by"/>
        "updateTime" column="update_time"/>
        "sysOrgCode" column="sys_org_code"/>
    
	
    "selectSysCustomFormById" parameterType="String" resultType="org.jeecg.modules.flowable.entity.SysCustomForm">
         select id, business_name, business_service, deploy_id, route_name,component,create_time, update_time, create_by, update_by, sys_org_code 
         from sys_custom_form where id = #{formId}
    
    
    "selectSysCustomFormByServiceName" parameterType="String" resultMap="sysCustomFormResult">
         select id, business_name, business_service, flow_name, deploy_id, route_name,component,create_time, update_time, create_by, update_by, sys_org_code 
         from sys_custom_form where business_service = #{serviceName}
    
    
    "updateCustom" parameterType="Object">
         update sys_custom_form set deploy_id= #{customFormVo.deployId}, flow_name=#{customFormVo.flowName} where id = #{customFormVo.id}
    
    
    "selectBussinessKeyByDeployId" parameterType="String" resultType="String">
         select id from sys_custom_form where deploy_id = #{deployid}
    
    

2、对流程启动也要修改，因为根据用户选择出来的id进行处理

 public Result startProcessInstanceByDataId(String dataId, String selectFlowId, String serviceName, Map variables) {
    	//提交审批的时候进行流程实例关联初始化
    	if (StringUtils.isEmpty(selectFlowId)){
            return Result.error("未找到关联流程selectFlowId："+selectFlowId);
        }
    	/*
        if (serviceName==null){
             return Result.error("未找到serviceName："+serviceName);
        }*/
        SysCustomForm sysCustomForm = sysCustomFormService.getById(selectFlowId);
        if(sysCustomForm ==null){
        	 return Result.error("未找到sysCustomForm："+serviceName);
        }
        //优先考虑自定义业务表是否关联流程，再看通用的表单流程关联表
        ProcessDefinition processDefinition;
        String deployId = sysCustomForm.getDeployId();
        if(StringUtils.isEmpty(deployId)) {
        	SysDeployForm sysDeployForm  = sysDeployFormService.selectSysDeployFormByFormId(sysCustomForm.getId());
            if(sysDeployForm ==null){          	
       	       return Result.error("自定义表单也没关联流程定义表,流程没定义关联自定义表单"+sysCustomForm.getId());
            }
            processDefinition = repositoryService.createProcessDefinitionQuery()
        		.parentDeploymentId(sysDeployForm.getDeployId()).latestVersion().singleResult();
        }
        else {
        	processDefinition = repositoryService.createProcessDefinitionQuery()
            		.parentDeploymentId(deployId).latestVersion().singleResult();
        }
        
        LambdaQueryWrapper flowMyBusinessLambdaQueryWrapper = new LambdaQueryWrapper<>();
        flowMyBusinessLambdaQueryWrapper.eq(FlowMyBusiness::getDataId, dataId);
        FlowMyBusiness business = flowMyBusinessService.getOne(flowMyBusinessLambdaQueryWrapper);
        if (business==null){
        	if(processDefinition==null) {
        		return Result.error("自定义表单也没关联流程定义表,流程没定义关联自定义表单"+sysCustomForm.getId());
        	}
        	boolean binit = flowCommonService.initActBusiness(sysCustomForm.getBusinessName(), dataId, serviceName, 
        	processDefinition.getKey(), processDefinition.getId(), sysCustomForm.getRouteName());
        	if(!binit) {
        		return Result.error("自定义表单也没关联流程定义表,流程没定义关联自定义表单"+sysCustomForm.getId());
        	}
            FlowMyBusiness businessnew = flowMyBusinessService.getOne(flowMyBusinessLambdaQueryWrapper);
           //流程实例关联初始化结束
            if (StrUtil.isNotBlank(businessnew.getProcessDefinitionId())){
              return this.startProcessInstanceById(businessnew.getProcessDefinitionId(),variables);
            }
            return this.startProcessInstanceByKey(businessnew.getProcessDefinitionKey(),variables);
        }
        else {
        	 return Result.error("已经存在这个dataid实例，不要重复申请："+dataId);
        }
        
    }

3、前端代码如下：
